LOCK rno'rnc'ron.

Application filed February 26, 1921. Serial No. 447,950.

. tectors; and I do hereby declarethe following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which itappertains to make and use the same I The lock mechanism of safes, vaults and analogous depositories for valuables, documents and papers usually'comprises a plu-. rality ofbolts, a bolt bar connecting the,

bolts for simultaneous operation thereof, and a lock device for securing the "boltbar in looking position. I

\Whenthe usual lock device'is actuated and releases the bolt bar, the latter may be moved and the door of the safe, vault or other depository opened.

The present invention interposes an im-, pediment to the movement of the bolt bar, thereby increasing the difiiculty of unauthorized opening of the safe, vaultand the like.

The invention consists of an auxiliary locking means adjunctive to the regular lock mechanism, whereby it becomes mandatory that the auxiliary locking means be operated to release the bolt bar or analogous part of the main lock works before the latter can be actuated to release the door so that the latter may be opened.

Other objects and advantages will i be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention, it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the specification,

Figure. 1 is an elevationof the inner side I Figure 3 is further detail. I

(lorrespondingand like parts are referredre 11'). the fellewmg description deaia by like reference characters. I y

The numeral 1 designates a .door such as commonly provided for safes and vaults, the same being equipped with the usual natedin the several views of the drawings I lock works embodying the ordinary bolt bar 2 which is operativelyconnected with! all thebolts-of the lock mechanism, whereby to effect'simi'iltaneous operation thereof. The bolt bar 2"coop'erates with the usual lock device .3, wherebythe same is made secure against movement when the door is closed and locked. t; i

--The present invention provides locking means for the bolt bar 2 independently of the usual lock device 3, whereby to add to the diificulty of unauthorized opening of the safe, vault or like depository. A lock device kis mounted upon the door 1 and may be of any type, preferably consisting of the, permutation variety. A rod5 cooperates with the lock 4 and is controlled in its movements thereby. Telescoping members 6 and 7 are interposed between the bolt bar 2 and the door so as to prevent movement of the bolt bar when the door is locked. The member 7' is connected at one end to the bolt bar 2 and its opposite end telescopes with the member. 6 which is made fast atone end to the bolt frame 8, or other convenient part of the door. vThe member 6 is tubular and the member 7 is slidable therein. An elongated opening or slot 9 is formed in a side of the member 6 and a latch lO is operable therethrough and cooperates with the parts 6 and 7 to prevent relative movement thereof in one direction, whereby to'securethe bolt bar 2 tion to lie within the member '6 to admit of unobstructedmovement of the member 7 so that the bolt bar 2 may be. operated 1n- ,the usual Inannerto throw the bolt of the .lock works and release the door after. the

lock 3 hasbeen operated in the usual way. The weight of the latch 10 maybe suflicient to throw the same into operative position. However, to insure erably attached at one end to the member 6, the opposite end coo crating with the latch 10. The member is slotted to re positive 'movement thereof aspring 12 is provided and is pref ceive the latch'10 which iscarried thereby.

When the door 3; is closed locked, the

latch 10 of the auxiliary locking mechanisin constituting the protector projects through the opening 9 ofthe member 6, thereby securing the member 7 and the bolt bar 2 connected therewith. bar 2 can be moved to effect opening of the safe, vault or like depository, the .lock l must be actuated toefi'ect release of the member 7. Should the bolt bar 2 be released fromthe lock 3 in any manner whatsoever, it cannot be moved without releasing it from the action of the auxiliary locking mechanism which is effected by nnivement oif the rod 5 after the lock 4 has been operated. It will thus be understood that the invention lIIlEBIPOSGSJll-l impediment and furtheradds to thedilticnlty ot' surreptitious opening of thesa'fe, vault or like part.

lVhatis claimed is:

1. In combination with a bolt meansfor control through actuation of a lock, abarrel and a rod associated with said loolt means saidrod'being slidable in said barrel, a latch on said rod, said barrel having a slot into Which the latch extends, the latch in said position being-adapted to abut-a wall "of said slot to function as a detent whereby unlocking movement of the. lock Before" the bolt assa-see means prevented and lock-operable means to move said latch out oi detaining relation with said barrel. the barrel wall servingto maintain the latch raised when disalig ned with said slot.

2. ncombinat-ion with a bolt means for control through actuation ot a lock, a rod and :rbarrel, associated with said bolt means, said rod. being slidable in said barrel, .aid rod having a slot a latch disp'osed within said slot and pirotedtothe real, said barrel havinga slot to 1e .ter with said slot, said latch being ad. v pend into the second slot and to abut a Wall thereof to function as a detent a sustaining spring for said latch on said barrel a rod connected to and adapted to raise said latch out of detaining relation with said barrel, lock meansto actuate the second mentioned rod, and the barrel-wall serving to maintain the latch raised when dis ali ned withsaid slot o1 the barrel.

i1 testimony whereof I aflix my signa ture in presence oi two witnesses.
